Toxic Pollutants Measured in Surface Water and Fish Collected from the Willamette River Basin by the Oregon Department of Environmental Quality (2008 – 2010)

Creator:: Coyle, Jim, Hamel, Allen, and Johnson, Ben
Abstract:: In 2008 the Oregon Department of Environmental Quality (ODEQ) initiated a program to monitor Oregon’s surface waters and aquatic biota for the presence of pollutants that pose risks to human and/or environmental health. ODEQ’s Toxics Monitoring Program was first implemented in the Willamette River Basin (WRB) between 2008 and 2010....

Soil quality assessment of Willamette Valley soils and root colonization potential by arbuscular mycorrhizal fungi

Creator:: Allen, Natalie M.
Abstract:: Interest in measuring soil quality continues to increase worldwide in view of demands on land productivity and the necessity to preserve soil resources, yet identification of suitable indicators for soil quality assessment is still evolving. This study adapted 10 biological, physical, and chemical indicators of soil quality identified by the...

Interannual variability in the Northern California Current food web structure: Changes in energy flow pathways and the role of forage fish, euphausiids, and jellyfish

Creator:: Ruzicka, James J., Brodeur, Richard D., Emmett, Robert L., Steele, John H., Zamon, Jeannette E., Morgan, Cheryl A., Thomas, Andrew C., and Wainwright, Thomas C.
Abstract:: The Northern California Current (NCC) is a seasonally productive and open ecosystem. It is home to both a diverse endemic community and to seasonally transient species. Productivity and food web structure vary seasonally, interannually, and decadally due to variability in coastal upwelling, climate-scale physical processes, and the migratory species entering...

Reproductive success and foraging ecology of the rusty blackbird on the Copper River Delta, Alaska

Creator:: Loomis, David M.
Abstract:: The Rusty Blackbird (Euphagus carolinus) has suffered significant population declines across its entire geographic range and the mechanisms associated with this decline are poorly understood. Although much of the Rusty Blackbird breeding habitat in Alaska has remained relatively unaltered by anthropogenic activities, this species continues to decline by an estimated...

Perceived Support, Knowledge Tacitness, and Provider Knowledge Sharing

Creator:: Swift, Michele L. and Virick, Meghna
Abstract:: This study provides a direct test of social exchange theory on knowledge sharing from the perspective of the provider by examining the role of both perceived coworker support (PCS) and perceived organizational support (POS) on the extent to which employees share their knowledge with their coworkers. Also examined is the...

Movement, dive behavior, and habitat-use of common murres (Uria aalge) in the Northern California Current System under variable ocean conditions

Creator:: Loredo, Stephanie A.
Abstract:: Year-round habitat use of marine predators provides knowledge of important marine areas throughout different life stages. Large-scale, environmental variability, both in space and time, causes changes in the behavior and distribution of marine predators that are important to quantify for conservation. In the Northern California Current System (NCCS), common murres...

The influence of houseplants in a child development center on young children's directed attention

Creator:: Harte, J. Davis
Abstract:: The near physical environment is believed to be an integral component in creating quality learning and classroom environments for young children. Free-choice play periods during preschool daily curriculums are a widespread component of preschool early childhood education. Research has demonstrated that the presence of houseplants may be a contributor to...

Spatial overlap between forage fishes and the large medusa Chrysaora fuscescens in the northern California Current region

Creator:: Brodeur, Richard D., Barceló, Caren, Robinson, Kelly L., Daly, Elizabeth A., and Ruzicka, James J.
Abstract:: As in many regions of the world, the shelf waters of the western United States have experienced large increases and high interannual variability in jellyfish populations in recent decades. The northern California Current (NCC) is a productive upwelling zone that is home to large populations of medusae, particularly during some...

Turning a Fish into a Brand: A Century of Rent-Seeking Strategies in the Tuna Canning Industry

Creator:: Mongruel, Rémi, Guillotreau, Patrice, García del Hoyo, Juan José, and Jiménez-Toribio, Ramón
Abstract:: Over the past century, the tuna canning industry has been dominated by a few big companies, some of them having changed of ownership or merged: these oligopolistic firms are the “big three” in the USA, Van Camp, Star Kist, and Bumble Bee, the French Saupiquet, the Italian Trinity Alimentari and...

Utilization of the Non-Native Seagrass, Zostera japonica, by Crab and Fish in Pacific Northwest Estuaries

Creator:: Sund, Daniel M.
Abstract:: The introduction of non-native species often results in fundamental changes in the structure and function of disturbed environments. In the Pacific Northwest (PNW), the introduced seagrass Zostera japonica is rapidly expanding in distribution, impacting stakeholders and public use of the intertidal. Z. japonica’s expansion has prompted a number of different...
